n v wringer which is more ffective for the purpose intended than are mop wringers of the aforementioned type as generally constructed.

A feature of the invention resides in a novel construction of mop head receiving receptacle whereby a greater twisting or wringing action,

than is possible with any other device with which I am familiar, is obtained.

A further feature of the invention resides in a novel construction which permits of the employment of a single blank of material for the formation of the mop head receiving receptacle, thus materially reducing the cost of manufacture of the device.

Still another feature of the invention resides in the combination of novel means for supporting the mop Wringer within a pail with which it is intended for use.

Still a further feature of the invention resides in a novel construction and arrangement of parts whereby the device may be employed in pails of different capacities in which as a matter of course, the open sides vary in diameter.

Other features will become apparent as the nature of the invention is better understood, for which purpose, reference will be had to the following specification and claim taken in connection with the accompanying drawings, in which,

Figure 1 is a perspective view of a conventional pail showing a mop wringer constructed in accordance with the present invention, in operative position therein,

Figure 2 is a detail sectional view on an enlarged scale, the view being taken on an enlarged scale,

Figure 3 is a perspective view on an enlarged scale illustrating the mop wringer removed with respect to the pail,

Figure 4 is a detail sectional view on an enlarged scale, taken substantially on the line 44 of Figure 3,

Figure 5 is a horizontal sectional view on an enlarged scale, the view being taken substantially on the line 5-5 of Figure 3; and,

Figure 6 is a plan view of the blank from which the mop head receiving receptacle is formed.

The mop head receiving receptacle is designated A, and it comprises a curved side wall B, a fiat side wall 0, and a bottom Wall D. The pail is designated by the reference character E.

The mop head receiving receptacle has a, rela- 5 tively large open end and a relatively small bottom wall D which is due, both to the angular position of the curved side wall B and the angular position of the flat side wall C.

Means is provided for supporting the mop head 10 receiving receptacle Within the open upper end of a pail and; this means, as herein illustrated, engagesthe rim of the pail at three points.

For, engagement with the rim of the pail at one point, there is a clip I 0 which is secured to the outer face of the curved wall at a point substantially midway of the ends of the top edge of the said curved side wall.

Extending throughout the length of the top edge, of the flat side wall C and projecting beyond the ends thereof there is a rigid bar H and the ends of this rigid bar II are in the form of right angular, extremities I2 The extended ends of the rigid bar H are of such length that the right angular extremities are spaced from their adjacent ends of both the curved and fiat side walls and this space permits of use of the device with pails of different diameters.

In supporting the device within the pail, the clip I0 engages the rim of the pail as illustrated in Figures 1 to 3 inclusive, the rigid rod I l, bridging the pail as illustrated in Figure 1.

The mop head receiving receptacle may be and preferably is formed from a single blank of material, which blank is illustrated in Figure 6 of the drawings.

Referring to said Figure 6, the blank is divided into a center section 20 and two integral end sections 2| by lines of fold designated 22 in said figure. The section 20 is of segmental shape having a curved outer edge 24 which forms the upper edge of the curved side wall when the blank is bent to finished form. The inner edge of the section 20 is defined by a line 25 and it is of such shape as to provide two projecting spaced ears 26.

The sections 2| are bent along the lines of fold designated 21 to provide two interlocking flanges 28, see Figure 4, and one of these flanges has a tongue extension 29,

The flat blank is first folded upon the lines of fold 22, after which the section 20 of the blank is bent into curved form. This bending of the section 2| into curved form brings the interlocking flanges into such position that they may be interlocked with each other as illustrated in Figure 4, in which position, they may be secured in any desired manner. The next step in the formation of the mop head receiving receptacle consists in bending the ears 26 into position where one overlies the other and then bending the tongue extension 29 into position where it lies beneath the overlapped ears 26, all as shown in Figure 5 of the drawings.

In the completed device, the section 2| forms the curved side wa1l;B, the two interlocked sections 2| forming the fiat side wall C, while the two overlapping ears form the bottom wall D, with the underlying tongue 29 providing a reinforcement or support for the bottom wall D.

The blank is of such shape that when folded to form the mop head receiving receptacle, the icontracted or neck portions 30 of the overlapping ears 26, form an opening 3| which is substantially circular in shape, while the end edges 32 of the sections 2|, being relatively narrow, form anelongated opening 33, both of said openings being located in the bottom Wall D with the opening 33 extending slightly upwardly in the flat side wall C as designated at 36 in Figure 2.

The section 2| has a rolled edge 31 formed by bending the blank along the dotted line 38, while the sections 2| are folded along the dotted lines 39 to provide portions 40 which embrace the rigid rod II, heretofore described.

By combining the curved side wall and the flat side wall, I provide corners or corner recesses 45 which materially aid in the attainment of a highly satisfactory wringing operation as will now be specifically described.

To wring a mop, the mop: head is placed in the mop head receiving receptacle and the mop handle is rotated to twist the mop head within the mop head receiving receptacle. The combination of the curved side wall and the flat side Wall producing the corner recesses or pockets 45, in the turning of the mop head, these corner pockets present an uneven inner surface which prevents free turning of the mop head within images the receptacle and thereby producing a greater wringing action than is possible of attainment with devices in which the inner surface of the mop head receiving recess is even or regular.

Another decided advantage derived from the combination curved and flat side walls is that this construction leaves substantially half or more of the top of the pail open for the free insertion of the mop head into the pail and by so constructing the device that the fiat side wall extends across the diameter of the pail, the said flat side wall facilitates the insertion of the mop head into the pail alongside of the mop wringer and its removal from the pail as well.

From the foregoing, it will be apparent that the present invention provides a new and improved mop wringer in which the several recited features have been accomplished and which is not only economical of manufacture, but has proven in actual use to be highly satisfactory in operation.

While the invention has been herein disclosed in its preferred form, it is to be understood that it is not to be limited to the construction herein shown and that it might be embodied in other forms without departing from the scope and spirit thereof.

Having thus described the invention, what is claimed and what it is desired to cover by Letters Patent of the United States, is;

A mop wringer comprising a mop head receptacle formed from a single blank of material and comprising a curved side wall, a fiat side wall and an open bottom wall, said bottom wall consisting of relatively narrow overlapping extensions projecting from the lower edge of the curved wall, and a relatively narrow tongue extending from the lower edge of the flat side wall and underlying the overlapping extensions which project from the lower edge of the curved wall said overlapping extensions and said tongue being spaced relatively to one another to provide the openings in said open bottom.
